Risen Energy adds SiC and full liquid cooling to new 131 kW/261 kWh C&I storage unit

Risen Energy has launched a 131 kW/261 kWh commercial-and-industrial (C&I) battery energy storage “all-in-one” unit featuring a full liquid-cooling architecture and a silicon carbide (SiC) power conversion stage, positioning the product as a higher-efficiency upgrade for behind-the-meter applications.

According to information released by the company, the new unit raises PCS rated power from 125 kW to 131 kW to better support high-frequency operating strategies such as two charge/two discharge cycles commonly used in C&I arbitrage and demand management.

A key change is the use of SiC MOSFETs in the PCS. Risen Energy claims the switching frequency is three times that of conventional IGBT solutions, cutting device losses by 40% and lifting PCS peak efficiency to 99.1%. It also reports a system round-trip efficiency of 90%.

Thermal management is built around “battery + PCS” dual liquid cooling. The company says the system can maintain full-power charging and discharging in hot conditions, reducing derating risk, while in cold weather it can recover PCS waste heat to warm battery cells and improve overall energy utilization.

On deployment, Risen Energy highlights a standardised cabinet and highly integrated electrical design. It claims single-cabinet installation can be completed in about 20 minutes, with a site-level deployment achievable within roughly 30 minutes, supported by pre-made harnesses and automatic device recognition after energization.

For protection and safety, the company points to an IP66 PCS (with optional IP67 pack protection) and a C4 anti-corrosion rating (C5 optional), alongside a multi-layer fire suppression package combining water-based suppression, aerosol, and optional pack-level firefighting.

Risen Energy also promotes AI-assisted operations via its Risen Cloud platform, including millisecond-level monitoring and AI-plus-EMS dispatch intended to optimise charging schedules and reduce reliance on manual operation.

In one illustrative profitability scenario, Risen Energy says the system could deliver an additional 12,210 kWh of annual cycled energy versus conventional air-cooled designs, translating into more than CNY9,000 (about $1,300) in incremental annual returns under a “330-day, two-charge/two-discharge” operating assumption.
